INTRODUCTION
En-bloc resection of bladder tumors is performed for bladder cancer with the goal of achieving precise tumor resection and providing an informative pathology specimen. We report the first case of a safely resected bladder paraganglioma by en-bloc resection.
CASE PRESENTATION
A 57-year-old woman presented with an incidental bladder tumor detected on computed tomography. Cystoscopy revealed a 10 mm submucosal tumor. Magnetic resonance imaging indicated a suspected bladder paraganglioma, whereas endocrinological tests showed no abnormalities. The tumor was completely resected in one piece without an intraoperative increase in blood pressure or bladder perforation. Pathological examination revealed a bladder paraganglioma with negative surgical margins. No evidence of recurrence was observed at 9 months follow-up.
CONCLUSION
En-bloc resection of bladder tumors may be a useful approach for selected cases of bladder paragangliomas, potentially decreasing the risk of intraoperative blood pressure fluctuations and ensuring complete tumor resection.
引言
整块切除膀胱肿瘤用于膀胱癌治疗，目的是实现精确的肿瘤切除并提供有诊断价值的病理标本。我们报告首例通过整块切除安全切除膀胱副神经节瘤的病例。
病例介绍
一名57岁女性在计算机断层扫描时偶然发现膀胱肿瘤。膀胱镜检查发现一个10毫米的黏膜下肿瘤。磁共振成像提示疑似膀胱副神经节瘤，而内分泌检查未发现异常。肿瘤被完整切除，术中血压未升高，也未发生膀胱穿孔。病理检查显示为膀胱副神经节瘤，手术切缘阴性。随访9个月未观察到复发迹象。
结论
对于某些膀胱副神经节瘤病例，整块切除膀胱肿瘤可能是一种有用的方法，有可能降低术中血压波动的风险并确保肿瘤完整切除。
